Abstract: A methodology is presented to characterize shape factor and surface area of coarse filter media. For several regular geometrical solids the variation of shape factor with a dimensionless parameter of maximum relationships were similar to that obtained by measurement on particles of crushed stone. Using this relationship, the shape factor and surface area of a stone particle could be estimated with a standard error of 4% from maximum dimension and weight, where the unit weight is known.
